Emanage on a 2002 Ecotec?
Monday, April 24, 2006 9:01 AM
Ok so since the GM reflash I dont believe will do much to help me, I'm thinking emanage, IM currently running 310cc injectors which are almost perfect under boost however out of boost its still running too rich and I have the infamous cold start problem where the car needs to warm up to 150 before I can drive it without stall

I know airtonics is running on a supercharged 02, so i know it can be done, mostly whats interesting me in it is the auto tune feature where I can enter in a desired AFR and it tells the injectors whatever to reach that AFR, is it really that easy?

Also will the emanage help lean the car out of boost to not dump so much fuel like it is now?

rodimus, why don't you think the gm reflash will help?


emanage can add or take away fuel and timing, making it better than an fmu/safc/afpr whatever other cheapass crap most people on here rely on... But, it was never designed with the gm pcm in mind so its a pain in the ass to set it up correctly in some cases... rich, even after figuring out something was wrong with the NyJbodies wiring diagram (they don't tell you to ground the additional injection ground wire), still never had anything but problems with it, but then again, he had an 04 with no open loop operation.

But seriously, even now with the cost of an emanage setup for boost, you're gonna be within a 100 bucks or so of hptuners anyway.... and hptuners can do more.

With emanage, you're still stuck with the stock rev limiter (and that blow of yours would probably shine with another 500 rpm), the speed limiter (not saying you're gonna need to remove it just yet but the more power you get the more that becomes a possibility.

I just talked to Airtonics the other day about emanage and hes still not able to use the additional injection map, still stuck using airflow adjustment which is probably throwin MAP codes (he'll correct me if i'm wrong cuz i didn't specifically ask him if it was or not).

But in all seriousness, if you have a piggyback, and the equivalent of a full standalone (which is basically what hptuners is, a standalone to flash a stock ecu), for close to the same price, emanage just isn't worth the trouble... and eventual troubleSHOOTING that you'll do.

My past experiance with the emanage was that it was alot better at adding fuel than it was at taking away. The base emange operates similar to an apexi safc in that it modifies MAP sensor signals to the stock ecu to alter fuel delivery. On an 02 you might have better luck with that than I had since you shouldn't have the PITA full time closed loop mode but it's still somewhat limited in what can be done b4 you start throwing MAP codes, which was one of the problems I had.

For adding fuel though it is great , again great as long as you car has an open loop. With the extra injection harness the emanage adds pulswidth to the stock injector pulswidth to keep them open longer.

I never really played with the autotuning feature that much but from what I understand it only adjusts the adjusted MAP table so you'd be limited to +or - 50% map values which probably would work for you. When I had the 310 injectors in my car with the emanage I was able to get it pretty close, and i didn't have any problems with it stalling at startup so it might be worth a shot. Then again these were just my experiances.... Take them for what you will.

Yea the HP tuners is something i been thinking about , I just want something where it adds fuel based on boost and not a specific rpm because depending on weather I make different boost levels, or have something set for a desired AFR at 100% TPS and it just does that

Im not sure what all system would be the best for acheiving that

read up on the hptuners stuff, you can set it up to have boost dependent fuel delivery.. the only ones that can't are the pre-00 Z24's and the 2.2 OHV's/2200's... because those ecus never had an operating system written for them for boost. All you'd have to do with hptuners is get the s/c reflash file and then you could modify it as you please. It would be a really good point to start from. I've been trying to read up more on the hptuners stuff but haven't really had time to sit down and really study it just yet.


And rich, jesus christ man, you're almost a legitimate postwhore lately! lol

Yea I've read up on the HP tuner stuff and honestly most of this stuff is beyond me , i been getting nowhere on how to get the GM reflash for my car since its an 02 and im not sure if i would need the new map thats with the gm eco kit
